Is That Classic Nick Fury on an ULTIMATES Cover?

Marvel's March 2013 solicitations, released on Wednesday, contained one significant surprise in the form of the Ultimate Comics Ultimates #22 cover, which featured a character that strongly resembled the classic version of Nick Fury.
Turns out, that's actually the cover to #21, out in February. To learn more, we asked Marvel if Dave Bullock's cover was meant to be taken literallly, and also if there was an amount of deliberate symmetry being explored, now that a new Nick Fury clearly inspired by the Ultimate version is firmly entrenched in the Marvel Universe.
